Did Islamic Extremists Target Incheon International Airport?

Reading the details of this bomb found at Incheon International Airport makes it sound like this may have been more of a hoax then some warning from a Islamic extremist group.  I am sure the ROK authorities are scouring over video footage to try and pin point who left the device and hopefully we will get answer soon:

Police said Saturday that they have found a warning message written in Arabic inside a box recently discovered at South Korea’s main airport that raised terror alarms in the country.

The message, which was written in Arabic on a sheet of paper half the size of A4, reads, “This is the last warning to you. God will punish.”

It was not a handwritten but a printed sentence with some grammatical errors, according to the police, who suspected that it could have been translated by a computer program or by a person whose Arabic skill is not that good.

The discovery was announced a day after the police found a box suspected to contain explosive devices in a men’s bathroom in Incheon International Airport.

The area was cordoned off, but no explosives or detonators were found, just with two butane canisters and one bottled water taped to it.

Also found inside the box, along with the warning message, were guitar strings, electric cords, batteries and some pieces of vegetables, the police said.  [Yonhap]
